Cardiometric control & monitoring in therapy: instrument for treatment correction.
Assessment of therapy quality

Dear readers!

Our Journal’s quest for scientific frontiers leads to publications on hot topics in research, and the current Journal issue is supporting this general rule. Following this way, we are presenting hereby one of the hottest themes: Cardiology in Oncology.

Review

Cardiotoxicity: a challenge for modern oncology

The article provides a modern vision of the problem of cardiotoxicity in oncology. Integrity and generality of nodal pathogenetic events in the body in case of carcinogenesis, antitumor therapy and cardiopathology are caused by similar mechanisms at different hierarchical levels. Identity of potential risk factors, including inflammation, aging, obesity, diabetes and smoking, has been noted.
Original research

Actions and effects of malignant tumor growth and chronic neurogenic pain exerted on the glutathione system in cardiac mitochondria in experimental animals

The aim hereof is to study the glutathione system peculiarities in the cardiac mitochondria in experimental animals against the background of a tumor process, chronic pain and the combined effect both of chronic pain and the tumor process.
Original research

The state of free-radicals procceses in cardiomyocytes in rats under the action of Doxorubicin and protection by Preductal

The aim of our research work was to investigate the state of the lipid peroxidation system – the antioxidant protection system (LPO-AOS) in heart tissue in rats received either Doxorubicin alone or in combination with Preductal premedication.
Original research

The state of hydrolytic processes in the myocardium and its draining lymphocytes in rats under the effect of Doxorubicin under protective Trimetazidine premedication

The aim hereof is to study the activity of cathepsin D (CatD), alkaline phosphatase (ALP) and acid phosphatase (AP), the antitryptic activity (ATA) of acid-stable inhibitors (ASI) in rats in heart tissue and its draining lymphocytes under introduction of Doxorubicin and protection with Trimetazidine.
Original research

Features of the psychosomatic state in lung cancer patients and psychopathophysiological aspects of cardiovascular diseases

The aim hereof is a comprehensive study of the mental, adaptive and hormonal status in patients with lung cancer with varying prevalence of the malignant process. The obtained results are compared with data on the psychosomatic state and subclinical disorders in the thyroid system in patients with cardiovascular diseases.
Original research

The prospects for applications of cardiometric approach in evaluation of cardiotoxicity under Anthracyclines therapy in patients with breast cancer

The aim is to study the action and effects of antitumor polychemotherapy (PCT) with Anthracyclines on the cardiovascular system performance in primary oncological patients with breast cancer (BC).
Essay

Cardiometry in oncology: new digital possibilities for analyzing the cardiovascular system state in cancer patients

The new high-tech era begins not with supply of an innovative product to the market, but rather with an intellectual leap in the field of open issues in fundamental engineering, healthcare and education. In the present essay, an example of the successful translation of mathematical, physics- and engineering-related philosophy into the digital platform of Cardiometry is discussed. The theory of hemodynamics, the laws of axiomatics, logic and adaptation can be expressed in terms of mathematics. The original analytical software used in PC-assisted device Cardiocode allows carrying out a phase analysis of the hemodynamics within an extended range.
Original research

Assessment of the efficacy of a peroral anticoagulant after surgical resection of gastric cancer

Patients suffering from gastric cancer have a high risk of postoperative thrombotic complications and often use anticoagulants. Direct oral anticoagulants absorb in the proximal region of the digestive tract. Consequently, a reduction in anticoagulating activity is possible.
Original research

Disorders of the cardiovascular system performance in the early post-castration period in patients with locally advanced cervical cancer and their correction with the low-dose xenon therapy

The aim hereof is to study the cardiovascular system disorders in the early post-castration period in patients with locally advanced cervical cancer and a possibility of correction of such disorders with the low-dose xenon therapy.
Short report

A brief analysis of the use of non-linear time-frequency filtering for processing ECG signalss

Some current trends of the use of non-linear time-frequency filtering approach to ECG signal processing are discussed herein. A brief review of an application potentiality of non-linear filtration is offered for long-term ECG signal processing. Possible problems of long-term monitoring, related to measurements interference and noise of ECG signal, are revealed. To eliminate the revealed problems, in further research, an implementation of a processing system using the non-linear-threshold time-frequency filtering method is planned. It is expected to improve an accuracy of cardiac data processing considering features of interference and measurement noise of different intensity.

Motion of blood formed elements in a pulsatile hemodynamic flow

This paper offers some results obtained in our studies on the motion of individual formed elements in blood with due regard of a pulsatile flow of the plasma in the blood vessels. An analysis of the process of the motion of the blood particles having different shapes in a pressure wave variable field of the pressure wave has been completed herein.
Original research

Effect of slow coronary flow on signal-averaged electrocardiogram

The slow flow coronary or decreased coronary TIMI flow rate is characterized by delayed pacification of coronary vessels in the absence of any evidence of obstruction coronary artery disease and is detected by coronary angiography. In the present study, we aimed to evaluate the effects of slow coronary artery flow on signal-averaged electrocardiogram (SAECG) as a possible indicator of increased risk for ventricular arrhythmias and sudden cardiac death.
Report

Functional state of the blood coagulation system in postsurgery period in patients with malignant tumors of the GI tract

The aim of our research work was to investigate the state of the lipid peroxidation system – the antioxidant protection system (LPO-AOS) in heart tissue in rats received either Doxorubicin alone or in combination with Preductal premedication.
Case report

Ruptured mycotic hepatic artery aneurysm associated with methicillin sensitive staphylococcal endocarditis

Hemobilia is a rare cause of upper gastrointestinal hemorrhage. Classical presentations of hemobilia are biliary colic, jaundice, hematochezia and melena. Persistent bleeding sometimes requires urgent therapeutic intervention, such as angiographic intervention or surgery. It may be secondary to trauma, inflammatory disorders, gallstones or tumors. Hepatic artery aneurysm rupture is a rare cause of gastrointestinal bleeding.
Short report

Metabolic processes evaluation in cardiac muscles on the basis of cardiometry

The article briefly discusses the cardiometric approach to the evaluation of metabolic processes in cardiac muscle. Reactions occurring during the various phases of the cardiac cycle, primarily in the QRS complex, are shown. The dynamics of energy processes occurring before and after physical load, as well as the reactions occurring during it, are presented. The ECG derivative is used.
